Drive belt

The drive belt transfers power to the engine’s electrical and cooling systems. A slipping drive belt results in decreased battery charging and reduced coolant circulation. It is important to replace a worn drive belt as soon as possible. The cost is very small and compared to an engine breakdown it is a very good investment. Drive belts should be correctly tensioned so that there is no more than 5–10 mm play between the pulleys. It is also very important that the drive belt is not split or frayed. The rubber used in Volvo Penta drive belts is unique. The belts have raw-cut open sides, with the rubber fibres arranged cross-wise. This gives both longitudinal pliability and lateral rigidity, qualities that result in better grip and precise seating in the pulleys.
